Description Cristian Rauth 2008-07-22 11:25:36 UTC

Gentoo 2008.0-r1 i686 LiveCD doesn´t boot on VIA Epia SP13000 (C3-2 Nehemia CPU)

System hangs during boot

After the message: "Uncompressing Linux... ok, booting the Kernel." I get this errormessage:

BUG: Int 6: CR2 00000000
EDI 00000000 ESI 00001000 EBP c068cf64 ESP c068cf3c

and so on ... 

Reproducible: Always

Steps to Reproduce:
1. Boot an Via Epia SP13000 system from Gentoo 2008.0-r1 i686 LiveCD
2. At the point where you can choose the Kernel Options, choose what ever you want   
   or hit just enter.
3. Wait a moment and then the errormessage pops up.

Actual Results:  
After the message: "Uncompressing Linux... ok, booting the Kernel." I get this errormessage:

I'm pretty sure the VIA C3 is one of the 586-like processors (missing just one instruction to be i686). Use the minimal instead.

Comment 2 Cristian Rauth 2008-07-22 14:34:47 UTC

Are you sure? 
The Via Nehemia C3-2 should be a 686-class processor.
It´s from CPU family 6

Can you test the minimal CD?

Comment 4 Cristian Rauth 2008-07-22 15:08:48 UTC

Booting from the x86 minimal CD is working fine.

installcd-2.6.24.config:CONFIG_M486=y
livecd-2.6.24.config:CONFIG_M686=y

That seems to lend credibility to my original statement.

Comment 6 Cristian Rauth 2008-07-22 18:29:54 UTC

OK, then lets close this bug.
Thanks for looking at this
